Within the history of the United States, who became the third U.S. President to be impeached?

Hitman seems awfully biased in his so-called answer. I've noticed it on many other occasions as well.

But he may become the first president to be impeached twice! And hopefully the first to be officially banned from running for office ever. He is a stain on our political system.

also the first ex-president to have been convicted of a felony - 34 felonies

Montrose MO, Benedict Donald is traitor and should be executed. It's a pity the assassin missed. He would have done America and the world a favor.
